Sean:
I'm not sure where you are getting that from my posts. You seem to think that I'm advocating a position that Mr. Homeowner should just suck it up and live with a constant rain of golf balls on to his home, cars and family. That's not what I'm suggesting at all.
I'm not talking about the actions or responsibility of individual golfers; rather, I'm talking about the property rights of a later home owner vis-a-vis a pre-existing golf course.
If a golfer hits his tee shot through Mr. Homeowner's window, the golfer is responsible for the damage. Likewise, if he wants to pursue those golfers who enter his land to retrieve balls for trespass, that is his right. I don't think any of that's in doubt at all.
And perhaps, if the problem is really as bad as Mr. Homeowner suggests it is, and enough members have to dip into their pockets to pay for damage, the members will decide to change the course (or come up with some other solution to mitigate the issue).
It's an entirely different question as to whether Mr. Homeowner is entitled to injunctive relief to force the golf club to alter its golf course when he knew or should have known of the the issue before purchasing the property. And you're right - he is suing the seller - and in my opinion, that suit is where his remedy, if any, should lie.*
*(in addition, of course, to any remedy against individual golfers who cause damage to his property, as noted above).
